Ear temperature measurement may be acceptable for observing trends in body temperature but is less useful in consistently identifying fevers. Monitoring internal body tc accurately requires invasive methods of measurement. As with rectal measurement sites tympanic thermometers may give slightly higher readings with the average temperature around 995 f. Temperature was the rectal temperature and the lowest temperature was the axillary temperature. 2 autonomic as well as behavioral responses to changes in temperature maintain homeostasis or a range of normal around 37 c. A measurement comparison of the new sensor with the rectal temperature revealed that the double sensor i differed up to 006 c from the average of the rectal temperature ii showed with increasing ambient temperatures increasing concordance correlation coefficients and iii exhibited a more rapid response to the core body temperature changes for all resting periods and at all ambient.
The di erence between the mean values for tympanic and rectal temperature was 02 c. These include the measurement site the reliability of the instrument and user technique pusnik and miklavec 2009. Until recently direct measurement of core body temperature required surgical insertion of a probe so a variety of indirect methods have commonly been used. Temporal measurements are closer to true core body temperature and provided that the probe has been properly positioned will give readings that are closer to average body temperatures of 986 f. The pulmonary artery catheter which measures blood temperature is considered the gold standard for measuring core temperatures. Climatic injuries including hypothermia hyperthermia and heat stroke are common in many sports activities.
1 core body temperature is regulated by both peripheral and central receptors that are integrated within the hypothalamus. 43 studied the tympanic membrane vicinity as the measurement site of core body. Body core temperature tc measurement for the sportsperson can influence individual performance and may help to prevent injuries. The measurement of core body temperature may seem simple but several issues affect the accuracy of the reading. The normal body temperature for an adult is around 986f 37c but every persons baseline body temperature is slightly different and may consistently be a little higher or lower.
